Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] see Figure 1-3 , the present invention provides a technical solution:

[0019] We took advantage of the property that yellow phosphorus is easily soluble in carbon disulfide (solvent), and operated through processes such as dissolution, filtration, and distillation during the experiment. The equipment used is: enamel stirred tank, centrifuge, reboiler, condenser, recovery device and other pilot devices to carry out the test), the progress is very smoo...

Abstract

The invention discloses a low-temperature solid-liquid separation method and formula for phosphorus sludge, and the separation method comprises a dissolution process, a low-temperature solid-liquid separation process, a rectification process, and the refining, rinsing, storage and packaging of a final product. In the process of processing and recycling products, physical properties of materials are used in the whole process, no chemical reaction or other products are generated in the process, full-sealing operation is basically achieved in the operation process, no pollution is caused on site, and the process is the most ideal process for solving the phosphorus sludge treatment process in the yellow phosphorus industry. After the technical breakthrough, the medicament formula is short of supply in the market, and the medicament formula has huge potential of leading the market and large profitability.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation of mud phosphorus, in particular to a method for low-temperature solid-liquid separation of mud phosphorus and a medicament formula. Background technique [0002] Sludge phosphorus is one of the main by-products produced in the production process of yellow phosphorus. It belongs to the hazardous solid waste in the phosphorus chemical industry. The treatment and utilization of sludge phosphorus is a very important issue in the production of yellow phosphorus. It not only affects the yellow phosphorus industry The recovery rate and production cost of phosphorus in production, more seriously, cause serious environmental pollution problems, so almost all domestic yellow phosphorus manufacturers are discussing the treatment and utilization of sludge phosphorus, in order to achieve good environmental benefits, economic benefits and Social benefits, so as to realize the strategic grand pl...
